CAR DOOR.

Application filed September To all 10/60/72 it may concern:

Be it known that I, WILLIAM E. WINE, a citizen of the United States, residing at To ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car Doors, of which the following is a specification.

This invention relates to doors for railway cars or the like and has among its objects to provide an improved form of door of the flanged plat-e type wherein the door will not be weakened by the application thereto of the door hinges. Other objects are to provide a door of light weight and low cost and one easy of repair.

With such objects in view, the invention consists of the formation, combination and arrangement of parts as will be herein described, and particularly as pointed out in the appended claims, which show a preferred embodiment of the invention.

In the accompanying drawings, Figure l is a plan view of the car door of the drop door type constructed in accordance with the principles of the present invention. This view shows the door as seen from the outside of the car. Figure 2 is a side eleva tional view of the same. Figure 8 is a fragmentary transverse sectional view of the same, taken on the line 3-3 of Figure 1. Figure 4L is a fragmentary side elevational view showing one of the door hinges in cross section, the plane of this view being inclicated by the line 4t-t of Figure Figure 5 is a fragmentary cross sectional view through a portion of the door and through one of the hinges, this view being taken on the line 55 of Figure Referring to these drawings, the door is denoted by the numeral 1, and is formed of a steel plate preferably having continuous marginal flanges 2. These flanges are provided in order to stiffen the door. and in some instances to co-operate with adjacent portions of the car body to form sealing means to prevent loss of lading. Such doors are ordinarily hinged to the car body and the door of the present embodiment, as shown. is provided with door hinges 3. which lie against the upper face of the door. It is a common. practice to supply such hinges to doors of this character, but they are frequently applied to the outer face of the door, and in cases where this is done with doors having out-turned marginal flanges, as shown in the present embodiment, it is neces- 2, 1922. Serial No. 585,967.

sary to either bend the hinge around the flange that extends outwardly at the hinged edge of the door, or as is frequently practiced, to pierce this flange and pass the hinges through openings in the flange. The first practice results in a weakness of the hinge, while the second practice results in a weakening of the door in the vicinity of the pierced openings in the flange. Both constructions are also more costly, and are not so readily repaired as the construction of the present embodiment now to be described.

In the present arrangement trough-like corrugations a are pressed into the inner face of the door, on in other words, into the face that is presented to the lading of the ca. These troughs extend continuously across the marginal flange, as at 5, where it occurs along the hinged edge of the door. he troughs need not extend entirely across the face of the door, but are of a length suitable to accommodate therewithin the door hinges The uppermost faces of the hinges are preferably flush with the top face of the door and the hinges may be secured to the door as by means of the rivets 6, which pass through the hinges and through the door plate. The marginal flange that is formed along the hinged edge of the door extends continuously and uninterrupted across the corrugated troughs and may be formed of uniform depth, if desired, thereby resulting in bowed-down portions, as indicated at T.

I have thus provided a door arrangement wherein the hinges are located on the face of the door, opposite to the face thereof from which the marginal flanges are outstanding. yet having the hinges flush with the plane of the door. The arrangement is one wherein a maximum of service will be obtained from the metal employed and constitutes in generai improvements over such doors as now constructed.

Having thus described is claimed is:

1. A door for the discharge opening of a railway car embodying a plate of sheet metal provided with a marginal, flange. a trough like corrugation pressed in the inner or lading face of the door, the same extending at least partly across the door and across the said marginal flange, and a hinge member disposed within the trough of the said corrugation.

2. A door for the discharge opening of a my invention. what railway car embodying a plate of sheet metal "having a trough likef corrugation formed in its face, the same extending inwardly of the plate from one edge thereof, a hinge member arranged in thetrough of the corrugation and secured to thedoor,

and a marginal flange formed along the said edge of the door plate, the same extending continuously across the said corrugation and outstanding from the plate in a direction opposite to the hinge-carrying face thereof.

In testimony whereof I afiix my signature.

WILLIAM E. WINE.
